PayPal’s share of UK internet visits in all categories was 53 times higher last week.

At the moment, Google Checkout is offering similar incentives to those it offered in the US – customers are given £10 off for purchase of £30 or more, so it remains to be seen whether their market share drops off after this offer ends.

Google Checkout will clearly have a job competing with PayPal, which has a dominant 25% share of the market. Traffic from eBay is responsible for much of PayPal’s business, and eBay users are not allowed to use Google’s payments service.
